SAFETY main MEANS.

My invention relates to an attachment to be employed in connection with the rollers of wringers, washing machines and the like where rollers are liable to injure the hands of the person operating the device or machine.

The general object of the invention is to provide an attachment which will cause an article to be fed to the squeezing rollers of a wringer, for example, without danger of the hands of the operator being injured at any time. More specifically the invention has for its object to provide a novel and practical assemblage for the indicated purpose which may be readily applied to a wringer or like device and readily detached when not required for use.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being-understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a perspective view of a wringer having my safety feed means associated therewith;

Figure 2 is a transverse vertical section in a plane indicated by the line 22 of Figure 1, showing the attachment in operation;

Figure 3 is a view similar to Figure 2 indicating the rollers of the attachment as out of operative contact with the wringer rollers.

Figure 4 is an end view of the attachment.

In carrying out in invention in practice in accordance with t e illustrated example, a suitable frame 10 is provided, here shown as U-shaped to present side uprights and a bottom crossbar. The frame in the illustrated form has a bail-like attachment 11 presenting a top crossbar 12 adapted to engage the wringer A of known form. The arrangementis such that when the bail 11 is engaged with the wringer the safety attachment will be suspended on said bail in a position to be thrown into driving engagement with the squeezing rollers 13 of the wringer. The lower end of the bail 11 has yokeshaped terminals 13 adapted to be engaged with the frame portion C of the wringer A, as indicated clearly in Figures 2 and 3.

Between the side uprights of the frame 10 is a drive roller 14, the shaft 15 of which is journaled in the sides of frame 10. The ar- Application filed September 30, 1926. Serial No. 138,757.

rangement permits the frame 10 to swin on the bail 11 to throw the roller 14 into rictional driving engagement with the lower squeezing roller B of the wringer. The shaft 15 passes through short, vertical slots 16 in frame 10 to permit the roller 14 to be moved into driving engagement with the lower one of the feed rollers 16 and 17, the shafts 18 and 19 of which also are journaled in the frame 10. The shaft 15 has connected thereto links 114, the offset ends of which links are secured to the pivots 22 of shelf 21.- The shaft 18 of the upper feed roller 16 passes through vertical slots 20 in the frame 10. Shelf 21 is provided pivoted at its inner end as at 22, to the sides of the frame 10, so that said shelf may be depressed. Coil springs 23 are pivoted each at one end to shaft 19 of the lower feed roller 17 and at.

the upper ends springs 23 are connected with the shaft 18 of the upper feed roller 16.

With the described device, when the bail 11' is engaged with the wringer A the frame 10 will e suspended in front of the squeezing rollers B. The user of the machine, applying slight pressure to the shelf 21, may move the drive roller 14 of the feed means into driving engagement with the lower squeezin I roller B as shown clearly in Figure 2. ghelf 21, when depressed causes the pivots 22 to be raised and to lift the links 114,'and thereby moves the shaft 15 and roller 14 to a position for said roller 14 to have frictional driving engagement with the feed roller 17.

With the roller 14 in contact with and driven by the lower roller B of the wringer and with the rollers 16 and 17 in close relation under the constant but light pressure exerted by the springs 23, an article to be wrung by the rollers B, such as indicated at D in Figures 1 and 2, is entered between the rollers 16 and 17 and will be drawn therethrough and between the rollers B, and the relief of the pressure exerted downwardly on the shelf 21 will instantly throw the roller 14 out of driven engagement with the wringer roller.

It will be noted that the top of the roller 14 turns outwardly toward shelf 21. The direction therefore is such that should the article D not readily reach the rollers B and drop between the bottom roller B and the roller 14, the turning of said roller 1.4 will cause said article D to be lifted and guided between the rollers B.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention, as defined in the appended claims.

What I claim is:

1. In a safety feed means for directing articles through rollers, a frame, means to swingably mount said frame adjacent to the rollers to be fed, feed rollers in said frame, a drive roller for the feed rollers also mounted in said frame, means to move the feed rollers into close relation and means to throw said drive roller into driving engagement with one of the first mentioned rollers.

2. A safety feed means including a frame, a bail on which said frame is suspended, said bail adapted to be engaged with a wringer, feed rollers in the frame, a drive roller in the frame, a shelf pivotally mounted on the frame,- springs connecting the shelf with, one of the second mentioned rollers, and links connecting the shelf with the drive roller.

I 3. A safety feed means of the character described, said means including a frame, means to support said frame ad3acent to rollers to be fed, feed rollers in said frame, one of said rollers being mounted to move toward or from the other of said feed rollsaid arms and with the trunnions on said drive roller on the frame for raising said drive roller with the depression of said board and cause said drive roller to have'driving contact with one of the feed rollers.
